Air conditioning and refrigeration is a field that deals with the design, installation, maintenance, and repair of systems that control temperature and humidity in buildings and industrial processes. In this article, we will discuss the mechanism of air conditioning and refrigeration, highlights of the field, entrance exams, admission criteria, eligibility, duration of the course, selection criteria, application process, fee, syllabus, salary and job opportunities, and career opportunities.
Air conditioning and refrigeration systems work on the principle of heat transfer. They remove heat from a space or substance and transfer it to the environment or another substance. The systems use refrigerants, which absorb heat when they evaporate and release heat when they condense. The refrigerants are compressed and expanded using various components such as compressors, condensers, evaporators, and expansion valves. The process is controlled by a thermostat that senses the temperature and humidity of the space or substance and adjusts the system accordingly.
Air conditioning and refrigeration is an essential field that ensures the comfort and safety of people and products in various industries.
The field is constantly evolving, and new technologies and techniques are being developed to improve efficiency and sustainability.
Skilled professionals in air conditioning and refrigeration are in high demand globally, and the field offers excellent career opportunities and salaries.
